ISUZU Clutch Release Bearing 8-94389416-1 8943894161 for NPR 4BD1
Precision-engineered OEM replacement clutch release bearing designed for ISUZU NPR series trucks with 4BD1 diesel engines. This critical component ensures smooth clutch disengagement and engagement for optimal transmission performance.
Product Overview
The ISUZU Clutch Release Bearing (OEM: 8-94389416-1 / 8943894161) serves as a core actuation element in the clutch system. When the driver depresses the clutch pedal, this bearing pushes against the clutch pressure plate diaphragm spring, enabling smooth power transmission disengagement and engagement.
Numbering Note: This product number is 8-94389416-1 / 8943894161. The same series also includes 8-94389416-0 / 8943894160. Cross-reference numbers include RCT432 and BRG465. Please verify the specific number based on actual vehicle configuration.
Working Principle
  • Disengagement Process: Hydraulic or mechanical force moves the release fork forward, positioning the bearing against the pressure plate diaphragm spring
  • Friction Reduction: Precision rolling bearing design allows outer ring rotation while inner ring remains stationary, minimizing friction and wear
  • Power Cut-off: Bearing pressure separates the pressure plate from clutch disc, interrupting power transmission for gear shifting
  • Engagement Process: Return spring retracts the bearing, allowing pressure plate to re-engage clutch disc and restore power transmission
Failure Symptoms
Symptom Probable Cause
"Squeaking" or "grinding" metallic noise when depressing clutch pedal Worn or poorly lubried bearing internals
Clutch pedal feels heavy and hard to press Sticking or severely worn release bearing; increased resistance
Clutch fails to disengage fully; difficult shifting, gear grinding Worn bearing reducing travel; pressure plate cannot fully disengage
Clutch shudder or vibration during driving Uneven bearing wear causing uneven pressure plate loading
Persistent metallic noise near transmission (noticeable at idle) Severely worn or damaged release bearing
